,MODE `OE CONSTRUCTING TI-IE BOTTOM PLATES AND FLUES OF OVENS IN COOKING i APPARATUS.

Specification of Letters Patent No. 2,503, dated March 23, 18452.

To all whom it may concern Be it known that I, JORDAN L. MoT'r, of the city of New York, in the State of New York, have invented cert-ain new and useful improvements` inthe manner of constructing a cooking stove or apparatus, which I denominate `the Tubular-Oven Cooking Stove or Apparatus; and I do hereby declare that the following is a full and exact description thereof.

The formof my cooking stove, or apparat-us, may be varied, but its distinguishing feature is the manner in which I conduct the draft under the oven, by means `of two, three, or more, tubes, and co-mbine these with the fines in front of, above, and behind, the oven.

In the accompanying drawings, Figure l, is a perspective view of a cooking stove of a common form, but having my tubular flues at its bottom. Fig. 2, represents the said tubular flues connected together by means of suitable end pieces, and Fig. 3, one of the end pieces, or castings, by which they are connected, and retained in place. Fig. et, shows the back of the oven, which is divided into three vertical fines, two of them descending, and one ascending. Fig. 5, is a horizontal section through the lower oven lines, in the line of Fig. 2. Fig. 6, is a vertical section of the stove, from front to back, through its middle.

A, A, is a feeder which may be used when coal is employed as fuel; B, a side door for sup} 3lying wood when that article is to be burnt. I, I2, and L, are the tubes or lines, which form the lower part of the oven, ythe bottom plate of the stove being sunk, or depressed, so as to admit said tubes, and being made in such a shape as to conform to them.

The draft from the fire first passes over t-he top of the oven through an upper fine,

` or boiler space, O, C, in the usual way. The

I", and I2, by means of the openings I, I, shown in Fig. a; the draft` passes along these tubes toward the front, as shown by the arrows in Fig. 5. The fore ends of the tubes I', I2, and L, open into a flue space K,- which extends from sideto side of the stove; and from this space the draft returns toward the back of the stove through the center, tubular oven iue L, and thence it ascends through t-he center, back flue E, to the smoke pipe F. When it is not desired to use the oven, o-r when the lire is first lighted, a direct communication to t-he smoke pipe, from the space C, may be opened by a valve G, as in many other stoves. J, is a hot-air space between the back of the fire chamber, and the fore oven plate.

The tubes I, I2, and L, I attach together by means of cast-iron end pieces I-I, H, Fig. 2, one of which, with its rims, or collars, for receiving these tubes, is shown separately at Fig. 3. The lower edges of these end pieces are made to conform in shape to the bottom plate of the stove, so as to insure a close joint, and to cause the draft to pass properly through them. I have represented these tubes as round, but they may be square, or in any other form that may be preferred. I have spoken, also, of using two, o-r three, tubes only, but their number may be increased; it is desirable, however, to have them large, or they may be liable to be obstructed, to impede the draft, and are not easily cleaned; they are to be lifted out in their combined or connected state, and to enable them to fit closely when in place, there are ledges along the upper edges of the end pieces I-I, H, as shown at a, a., more distinctly in Fig. 6. The tubes may be made of sheet-iron, and by put-ting them together in t-he manner described, by means of the connecting pieces II, they may be readily removed, cleaned, and replaced. This tubular form of the lower portion of the oven greatly increases the temperature of the air contained in it, by the increased radiation and communication of heat from so large a portion of tubular surface; and a much smaller quantity is lost by radiation from the bottom plate of the stove. A grated bottom may be placed over the tubes, to support dishes, or other articles, in the oven.

Having thus, fully described the nature of my improved tubular-oven cooking stove,

'said oven flues open.

2. I claim, also, the manner of arranging and combining the lower oven flues together,

by means of the end pieces and collars H,

II, so as to render them removable at pleasure, for the purpose of cleaning, or repairing, them, and I do not intend to limit myself to any particular form, or construction,

of the stove, or cooking apparatus, ink which 20 I apply my tubular flues to constitute the lower part of an oven, but I claim the using, or combining, them, substantially in the manner set forth, with any kind of cooking sto-ve, Caboose, or range, which is furnished 2 with an oven, or with ovens, and 1n which they can be conveniently employed.
